NAME

slapo-valsort - Value Sorting overlay to slapd

SYNOPSIS

/etc/ldap/slapd.conf

DESCRIPTION

The Value Sorting overlay can be used with a backend database to sort
the values of specific multi-valued attributes within a subtree. The
sorting occurs whenever the attributes are returned in a search
response.
Sorting can be specified in ascending or descending order, using either
numeric or alphanumeric sort methods. Additionally, a "weighted" sort
can be specified, which uses a numeric weight prepended to the
attribute values. The weighted sort is always performed in ascending
order, but may be combined with the other methods for values that all
have equal weights. The weight is specified by prepending an integer
weight {<weight>} in front of each value of the attribute for which
weighted sorting is desired. This weighting factor is stripped off and
never returned in search results.

CONFIGURATION

These slapd.conf options apply to the Value Sorting overlay. They
should appear after the overlay directive.
valsort-attr <attribute> <baseDN> (<sort-method> | weighted [<sort-method>])
Configure a sorting method for the specified attribute in the
subtree rooted at baseDN. The sort-method may be one of alpha-ascend, alpha-descend, numeric-ascend, or numeric-descend. If
the special weighted method is specified, a secondary sort-method may also be specified. It is an error to specify an
alphanumeric sort-method for an attribute with Integer or
NumericString syntax, and it is an error to specify a numeric
sort-method for an attribute with a syntax other than Integer or
NumericString.
